Probability-theoretical simulation of creep in uniaxial tension of specimens

The finite expression for relative damage of the specimen material against the total inelastic strain and the differential equation of creep wherein the creep rate is represented by the sum of two terms were deduced. The finite expression for relative damage and the equation of creep contain eight coefficients whose fitting by the method of quadratic residual minimization could provide good agreement between calculated and experimental creep curves for different materials. The divergence of experimental creep curves for many materials known from the literature is of occasional unforeseen nature, it can be quantitatively described with a certain set of coefficients, i.e., assuming that each one is essentially a random value.
